Optimum Nutrition’s HMB 1000 contains pure hydroxy methylbutyrate, a metabolite of the essential amino acid L-leucine. L-leucine, the king of the BCAAs, was studied extensively in order to determine what makes it so anabolic. Research suggests that it may be from L-leucine’s HMB metabolites, which are produced when L-leucine is metabolized in the body.

HMB 1000 is recommended for over-trained bodybuilders, high-intensity athletes and those who train more than once a day. It has been shown to significantly increase protein synthesis in muscle tissue and possesses extreme anti-catabolic properties. HMB 1000 can help bodybuilders recover much faster and grow tissue at lightning fast speeds, allowing more gym time and less down time. HMB 1000 can also be used to preserve and even build lean muscle by dieters who are cutting their calories to very low levels. In other words, HMB helps build lean muscle, and whether you’re bulking, cutting or just maintaining, HMB 1000 can help you get bigger, leaner and stronger. Each capsule of HMB 1000 contains 1 gram of HMB, the highest concentration available on the market.

Good product

Im not quite sure if the quality of HBM can vary from manufacturer to manufacturer but this one seems to be like any other brand Ive tried, Im a big fan of ON product, they are very good quality, the only advantage I see with the HMB is that I can only take 1 capsule instead than 4-5 from other manufacturers

Good for Cutting

Good in combination with other things, great for keeping mass when cutting, requires more than the stated dose for all positive effects. Enjoy.

Keep Your Gains

Im not 100% sure this stuff works, I have tried it multiple times, but I always use it during a cutting phase as its supposed to help you keep your muscle while cutting calories.... but thats the thing, I always combine it with a healthier low carb high protein diet. Im not sure if its the diet or the pills, but either way, when I take it I look great.

Ridiculous lean muscle gains - HMB is legit...

HMB rocks. The research is solid, the science is solid, and the idea simply makes sense. HMB is a super potent l-leucine metabolite and it works. I've always been a fan of taking l-lecuine powder and I've noticed gains, but nothing like the gains I've gotten from HMB. I've been taking this stuff everyday for about 3 weeks now and I feel absolutely wrecked in and outside of the gym. I feel like everything I eat is being turned into muscle. I've jumped from 178 to 188 pounds and look leaner, and although I'm aware that you can't gain 10 pounds of lean muscle in 3 weeks, I'd be willing to bet I've gained 2 pounds of lean muscle, 4-5 pounds of water and maybe 2-3 pounds of ongoing digesting food weight from eating a lot more. Heck, who cares how much muscle I gained, I look bigger and more vascular and that's all that really matters to me. The only downside is that I wish I knew about this product 3 years ago...I can only imagine how much more lean mass I'd be carrying around.
